Hmmm - just like IBOC is 'QRM' for FM reception?

SW broadcasting is funded so that listeners can hear programs, not for the
benefit of amateur DXers.

DRM lets the intended listeners actually hear those programs clearly, and
tune them in easily. It sounds like you don't like it cause it sounds like
noise on your (probably highly expensive) set-up, and you like the tuning
process to be as difficult as possible.

Yes, without co-ordination there may be interefernce problems during the
transmition period, but the sooner the world goes DRM the better
international radio broadcastings prospects IMHO.


Perhaps you will tell us how the intended audiences of most shortwave
programming will be able to obtain these DRM receivers? Since most of these
broadcasts are intended for audiences outside their own countries, and for
other than their own expatriots (e.g. third world or oppressed populations),
those audiences are not likely to be able to afford (even if they could
obtain) such radios. Ordinary AM shortwave could be received with nothing
more than a few meters of wire, a variable capacitor (and even a fixed one
will work, depending upon design), a diode and an earphone. Reception of DRM
requires technology that is not available to much of the world.
